GPS Tracks in Google Earth

One of the features in GPS Speedreader I like is the ability to export GPS tracks to Google Earth to create pretty "crayon artwork", as Fangy call the images. Here's an example:

There are a few options to customize what you see:

For example, you can set a minimum speed, so that parts where you were going slow are all shown in the same color. A variety of different color schemes are also available. Here's the "high contrast" colors for the same track:

For the lower graph, I had selected the "Include time stamps and speeds" checkbox in the export options. This enables the time line in Google Earth, so you can "play" your tracks. It also write the doppler speed data to the exported file, which you can see as a graph at the bottom of the image (to see the graph, you have to right-click on the "Speed graphs" item in the side bar, and select "Show elevation profile"; then you'll have to click on the "Doppler speeds" in the graph panel). The speed graph also reacts to moving the mouse over it by showing an arrow with the speeds in the image above. You can also select regions in the graph to get average speeds for the region. Go ahead and play with it - downloads are free at https://ecwindfest.org/GPS/GPSSpeedreader.html.

Another new feature in the just-released version 1.2.8 is support for .sbn files from Locosys GT-31 GPS devices.
